Question

Which wavelength(s) would you use to detect the following?

1) Visible light
2) Ultraviolet light
3) Infrared light
4) X-rays

Answer 1

Visible light can be detected by the human eye, while ultraviolet light, infrared light, and X-rays require special detectors and cameras.

Step-by-step explanation:

The wavelengths used to detect different types of light are as follows:

1. Visible light: The human eye can detect visible light, which has wavelengths ranging from around 400 to 700 nanometers.
2. Ultraviolet light: Ultraviolet light has shorter wavelengths than visible light, typically in the range of 10 to 400 nanometers. Special UV detectors and cameras are used to detect UV light.
3. Infrared light: Infrared light has longer wavelengths than visible light, typically in the range of 700 nanometers to 1 millimeter. Heat sensors and infrared cameras are used to detect infrared light.
4. X-rays: X-rays have very short wavelengths, typically ranging from 0.01 to 10 nanometers. Special X-ray machines and detectors are used to detect X-rays.
